OpenDocument Reader

OpenDocument Reader is a mobile application designed for viewing and editing documents created with LibreOffice and OpenOffice. Available for both Android and iOS devices, it enables users to access, read, and make basic modifications to Open Document Format (ODF) files such as ODT (text), ODS (spreadsheets), ODP (presentations), and ODG (drawings) while on the go. The app addresses the need for mobile access to office documents, supporting tasks like reviewing notes, searching for keywords, and fixing typos directly from a mobile device.

The application offers a range of features including the ability to open password-protected documents, search and highlight terms within documents, print files when connected to a printer, read in fullscreen mode to minimize distractions, and select or copy text. Users can also listen to documents read aloud using integrated Text-To-Speech functionality. OpenDocument Reader is fully offline capable, allowing document access and editing without an internet connection. Documents can be opened from within other apps, with integrations supported for services such as GMail, Google Drive, iCloud, OneDrive, Nextcloud, Box.net, Dropbox, and others. Alternatively, users can browse and open files locally using the app’s file explorer.

Beyond ODF files, the app aims to support a variety of additional formats, including PDF, ZIP archives, common image and video formats, audio files, text files such as CSV and TXT, Microsoft Office formats (DOC, DOCX, XLS, XLSX, PPT, PPTX), Apple iWork files, PostScript (EPS), AutoCAD (DXF), and Photoshop (PSD). The application is open source and developed in Austria. It is not affiliated with OpenOffice, LibreOffice, or similar projects.

OpenDocument Reader is free to use and displays ads to support its development, with an option to temporarily remove ads via the in-app menu. Feedback from users is encouraged through email. This tool provides a solution for individuals seeking to manage, view, and perform basic editing on a broad range of document types directly from their mobile devices.
